What is the largest mass of copper sulphate which can be dissolved in 50g of water at 60 degrees centigrade?

The solubility of copper sulfate in water at 60 degrees Celsius is approximately 203 g/L. Therefore, in 50g of water, the maximum mass of copper sulfate that can dissolve would be 203g/L x 0.05 L = 10.15g.


How much hydrogyen will be formed by the reaction with 50g of zinc?

Do you mean this reaction? Zn + 2HCl -> ZnCl2 + H2 I will assume zinc is limiting. 50 grams Zn (1 mole Zn/65.41 grams)(1 mole H2/1 mole Zn)(2.016 grams/1 mole H2) = 1.5 grams of hydrogen gas


What mass of potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 grams of water at 313K?

At 313K, the solubility of potassium nitrate in water is approximately 62g/100g of water. To form a saturated solution in 50g of water, you would need roughly 31g of potassium nitrate.


What is the ratio of the mass in grams of magnesium used to the mass in grams of oxygen that reacted?

Balanced Equation: 2Mg + O2 ---> 2MgO Givens: 15.0 grams Mg 5.00 grams O2 Atomic mass of O2- 32.0 grams Atomic mass of Mg- 24.3 grams Molecular mass- 40.3 MgO Ratio- 2 moles : 1 mole : 2 mole First you have to determine the limiting reactant by converting to moles: 15.0 g / (24.3 g) = .617 moles Mg 5.00 g / (32.0 g) = .156 moles O2 Because there is less of the oxygen, it is the limiting reactant and what the rest of the problem will be based on. For the second part, you are given grams of oxygen and you are converting it to grams of magnesium oxide. 5.00 grams O2 / (32.0 grams O2)


How many grams of sodium nitrate will dissolve in 50 g of water at 60C?

Solubility of NaNO3 is 1.25 kg/kgwater. There are solubility vs temperature curve of many sodium salt available in the internet and text book.
